This invention relates to Certain new and useful improvements in registers and ventilators, and particularly to such registers as rest against the side wall of the room.

The object of the invention is to construct a simple and efiective means to provide a tight fit between the registerand the side wall for the purpose of preventing any dust indeed that the side .wall of a room is made so accurately that the ordinary register will fit so uniformly against the same as to make a sufficiently tight joint to prevent dust laden air from escaping and the consequent streaking of the wall. Consequently, it is the purpose of my invention to provide means to prevent this. 7

In the' accompanying drawing I have shown my invention as embodied in a'socalled base-board register; that is to say, a

Q register that is fitted against the side wall at the base, theclower edge of the register resting on the floor, but, as will be obvious, the invention is applicable to any form of side wall register whether the same be located at or above the base.

In the drawings- 7 Fig. 1 is a front elevation of a base-board 7 register a's'it would appear in place;

I Fig. 2 is a rear elevation of the register frame detached, the center perforated panel being removed and part of the packing be-- ing removed; 7 p

'Fig; 3 is a relatively enlarged cross-section on the line 3-3 of Fig; 1.

1 represents the frame of the register which has a rearwardly directed flange 2 around its outer edge which is designed to bear through. In the formfshown, this center plate is indicated at 5, and is provided with ong, vertical, closely arranged slotted openings. The number, size and shape of these openings may be varied as desired,and the center plate' rna y .be separate or integral with the-frame 1 as desired! The framel is also.

sog'inLI'nois, A conronarrontor. nnLn- 1' provided with a relatively short rearwardly directedflange 6 whichis designed to fit into the air duct 7, which is usually of tin, and

is #located in the Wall opening in position t0.-receive the. registenqyIt is seldom indeed thatsuch a close fitcan bem'ade between'the' flange-6 andthef'air'duct 7 that air passing;

through theduct toward the register will not leak around the flange 6. In Fig 311 have shown a: 'slight space. such as will almost:

invariably be found to existsomewhere between the flange 6 and the duct 7.. Thus, air

escaping through this space will, unless prevented, continue on and escape past 'theflange' 2 and cause a streaking of said wall. .It is the purpose of my'invention to provide simple and effective means to prevent this streaking, To that end I provide a yieldingly mounted, relatively. soft .pad or the like 8 just-adjacent the flange 2 whereit bears against the wall whichis so designed that it will yieldingly press against the wall 3 to form a suficiently tight joint or packing to prevent air escaping past the flange 2.. .In the particular form shown, the pad 8 may be" made of thick felt and, may be mounted on a yielding orspring-like support 9 which is secured in any desired manner, asby solder, to the inside of the flange 2Ythe packing edge of said support being spaced away from said flange, j The pad 8 may be securedto its support 9 in anyd'esired manner as by rivets 10; The support is so formed that it will hold the packing pad normally in such position as to press with reasonable snugne'ss against the wall 3 when the register is secured in -place,-said pad being provided wherever there is danger of leakage past the flange 2 so as to cause through the frame '1 and through openings or passages 12 in the pad supporting means, the screws themselves passing on into the studdingindicated at 14, this bei'ng one common means employedfor the securing of side 7 Wall registers in place.

While I have described my invention in one preferred form, I Wish itunderstood that various modifications and arrangements can be made from that shown hereinwit'hout departing from the spirit of the invention or the scope of the following claims.

lVhat Iclaim is:

1. In a .side wall register, a fnamescom structed at its outer edge to rest against the V side Wall, a yielding packing adjacent to the Wall bearing edge of said frame, and

yielding means for supporting saidpacking.

2. In a register, a frame, a fiangeat the outer edge of said frame,"another flange'aitheinner edge of sald frame, a packing between said flanges and atlthe rear of said frame and a yielding support for said packin'g. 7

3. In a register, a frame, a flange "at the outer (edge of sand frame, another flange at the inner edge of said frame, a yielding pack;

ing between said flanges and atthe rear of said frame an d a yielding; support for said yielding packing.
